This post show how Arduino Uno + RFID-RC522 (RFID reader) to dump info of RFID key and RFID card, using Arduino RFID Library for MFRC522.
Arduino library for MFRC522 and other RFID RC522 based modules (https://github.com/miguelbalboa/rfid) read and write different types of Radio-Frequency IDentification (RFID) cards on your Arduino using a RC522 based reader connected via the Serial Peripheral Interface (SPI) interface.
Install MFRC522 library to Arduino IDE:
You can download ZIP file from the library web page, and it to Arduino library, read the video below. After library added, it will be in the folder your_Documents\Arduino\libraries\,
and fritzing parts is in your_Documents\Arduino\libraries\rfid-master\doc\fritzing\.
Connect Arduino Uno and RFID-RF522 module:
In Arduino IDE, Open Example of DumpInfo in MFRC522:
/*
* ----------------------------------------------------------------------------
* This is a MFRC522 library example; see https://github.com/miguelbalboa/rfid
* for further details and other examples.
*
* NOTE: The library file MFRC522.h has a lot of useful info. Please read it.
*
* Released into the public domain.
* ----------------------------------------------------------------------------
* Example sketch/program showing how to read data from a PICC (that is: a RFID
* Tag or Card) using a MFRC522 based RFID Reader on the Arduino SPI interface.
*
* When the Arduino and the MFRC522 module are connected (see the pin layout
* below), load this sketch into Arduino IDE then verify/compile and upload it.
* To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M).
* When you present a PICC (that is: a RFID Tag or Card) at reading distance
* of the MFRC522 Reader/PCD, the serial output will show the ID/UID, type and
* any data blocks it can read. Note: you may see "Timeout in communication"
* messages when removing the PICC from reading distance too early.
*
* If your reader supports it, this sketch/program will read all the PICCs
* presented (that is: multiple tag reading). So if you stack two or more
* PICCs on top of each other and present them to the reader, it will first
* output all details of the first and then the next PICC. Note that this
* may take some time as all data blocks are dumped, so keep the PICCs at
* reading distance until complete.
*

bro is there any difference between RFID card ready and your project?
